What's going on here?

The absolute rankings are interesting for large scale comparisons but when you want to know about two
specific languages it's much more informative to look at how the two fare when they go directly head to
head.

Here are all the statements which we've got enough comparisons between
Mathematica
and
C#
to be meaningful and which of the two our users picked.

The order in which we're presenting them is a little arbitrary (sorry), but we've tried to put the things
which they're both good at first so as to give you the most interesting picture of it.

It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.
